Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a threshing waste straw processing mechanism that is mainly installed in a combine harvester and is used. The present invention relates to a constructed threshing straw processing mechanism.

[Conventional technology]

This type of threshing waste straw processing mechanism transports the waste straw after threshing in a horizontal position and supplies it to the waste straw bundling device on the side of the waste straw plant base side of the waste straw conveyance path. The present applicant has previously proposed a device that is provided with an endless rotating band with protrusions that acts on the end of the plant of the waste straw being conveyed to bring the waste straw closer to the head side and convey it toward the rear. (Refer to Utility Model Application Publication No. 59-73151).

[The problem that the idea attempts to solve]

In the conventional structure described above, even if there is a slight difference in the position of the end of the stock due to the length of the removed straw, the end of the plant is transported to a fixed position relative to the binding device by the straw collecting action of the endless rotating belt. Although it is possible to perform binding with a constant length from the end to the binding position (binding length), the binding length can be changed depending on the length of the waste straw, the post-processing of the waste straw, etc. It had become impossible to do so.

In addition, because the plants were aligned only by the action of the endless rotating band toward the tip side, it was difficult, for example, to push some of the waste straw that protruded from the end of the plant in the group of removed straws and align them toward the tip side. In some cases, stocks were tied up without sufficient stock allocation.

The present invention was developed in order to solve the problems of the conventional structure, and it is possible to tie the waste straw sent out from the waste straw conveying device in a sideways position to the desired bundling length and to keep the stocks aligned. The purpose is to enable binding processing in good condition.

[Means to solve the problem]

The characteristic structure of the present invention to achieve the above purpose is as follows:
After threshing, the waste straw is transported in a sideways position and is supplied to the waste straw binding device. An endless rotating band with protrusions that act to move the waste straw toward the tip side and convey it rearward is provided, and the endless rotating band conveys the waste straw to a lateral part of the stock bottom side of the waste straw binding device. We have installed a stock alignment device that knocks down the ends of the waste straw that has been used.
In addition, the endless rotating band with the protrusion and the stock alignment device are configured to be adjustable in position in the direction of the straw culm.

[Effect]

According to the above configuration, the waste straw sent out from the waste straw conveying device in a sideways posture is pushed toward the tip side by the endless rotation band with projections, and is sent to the rear. The waste straw is supplied to a binding device, and even if the position of the end of the stock when it starts acting on the endless rotating belt differs depending on the length of the removed straw, the end of the stock at the end of conveyance of the endless rotating belt may be different. The position is determined to be a predetermined distance away from the binding position of the binding device.

The waste straw that is supplied to the waste straw binding device in such a manner that the stock end is located at a predetermined position is in a state where the stock is roughly aligned. They are received from the side, some of the protruding stocks are pushed in, and the bundling is performed after the stocks are sufficiently arranged.

In addition, by adjusting the position of the endless rotating band and the stock alignment device in the direction of the waste straw culm, the bundling position relative to the waste straw, that is, the bundling length, can be adjusted and set, and the stock alignment at that bundling length can be adjusted. An alignment effect can be appropriately applied.

[Effect of idea]

As explained above, according to the present invention, even if there is a slight difference in the position of the end of the straw being conveyed, the bundling length is constant due to the action of the endless rotating band toward the tip side. Not only can the bundling be performed with good stock alignment, but by adjusting the position of the endless rotating belt and stock alignment device in the direction of the straw removal culm, it is possible to tie the bundling with sufficient length by changing the bundling length. Now I can do it well with stocks in stock.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figures 2 and 3, the threshing straw carried out from the handling room (not shown) is placed at the rear of the threshing device 1 in a horizontal position, and transported by holding the stock side at the rear of the machine. A shredding device 5 which is provided with the device 2 and which shreds and discharges threshed waste straw with a disk cutter 4;
A waste straw binding device 6 that ties threshed waste straw in a set amount in a sideways posture and releases it to the rear of the machine, and a waste straw bundle from this waste straw binding device 6 is placed at a location corresponding to one horizontal side at the rear of the machine. A conveying/discharging device 7 that pinches, conveys, and releases and drops grains while standing in a field is connected to a threshing device 1.
is installed at the rear of the lid body 8, and by vertically swinging the lid body 8 around the axis _P1 , the threshed waste straw is released in a shredded state.
A threshing/discharging straw processing mechanism for a combine harvester is constructed, which allows the long straw to be placed upright in a field in a tied state.

A connecting frame is provided on the side of the waste straw conveyance path R for supplying the waste straw to the binding space in a sideways posture, and connects drive rollers 9 and idle rollers 10, which are distributed on the upper side and the lower side of the conveyance path R. 11 so as to be rotatably supported around the vertical axis, and the endless rotation band 12 acting on the stock end of the waste straw present in the conveyance path R is conveyed to the waste straw binding space side. Both the rollers 9 and 10 are rotated so as to be driven to rotate.
It is wrapped around. Further, the connecting frame 11 is made swingable around the axis 9a of the drive roller 9, and a link 13 fixed to the swinging fulcrum side of the connecting frame 11 and a lever 14 of the control section (not shown)
are connected by a push-pull wire W to form an operating mechanism, and by swinging the lever 14, the endless rotation band 12 is adjusted to swing around the axis 9a, thereby eliminating the conveying surface. It is designed so that the position can be changed in the direction of the straw culm.

At the terminal end of the endless rotation band 12, that is, at the front end of the bundling space, there is a stock alignment board 15 that swings about the axis _P2 as a fulcrum and strikes the stock ends of the waste straw.
A stock alignment device 25 is provided which includes a crank mechanism 16 that swings the stock arrangement device 25. Further, the axis _P2 of the stock alignment plate 15 is located on the link 13, and moves with the swinging of the endless rotation band 12, so that the swinging position of the stock alignment plate 15 can be changed in the lateral direction. It is set as.
Further, by mounting a crank mechanism 16 on the spline shaft 24 for swinging the stock alignment plate 15, the crank mechanism 16 can be moved as the swinging position of the stock alignment plate 15 is changed. The threshed waste straw carried into the bundling space is leveled by beating the ends of the stock lining plate 15 on the stock lining board 15, and then moved to the door 18 by the packer 17.
After being raked to the side, they are tied together and can be dropped and released in a standing position in the field by means of a conveyance and release device 7 extending to the rear.

The scraper 17 is synchronized so that the waste straw tying device 6 performs one tying operation every two times, and the stock alignment plate 15 strikes the base end of the waste straw three times during that time. When the stock alignment plate 15 reaches the stroke end, the packer 17 is positioned at one of three locations: before and after the plowing start position, and at the most compressed position.

Next, FIG. 4 shows the transmission system of the threshing and waste straw processing section in the combine harvester of this embodiment.
